Okay, we all have our weak area and I admit, half a semester of high school electrical didn't get me very far. So, at the risk of posing a noob question, did my new Rottendog WPC driver board come with the wrong fuses?

I installed one of these in my latest TZ project. I'm buying pins for the long term so this is an investment for me. A few days ago during Powerbal Mania all solenoids went dead... I blew a fuse. The game is at work so I left it, went home and I grabbed my manual. F112 being the likely culprit, I bring a 7amp SloBlo in the next morning. I yank out F112 and sure enough, it's dead. I take a closer look and the Rottendog board had a 5amp fuse there. Okay, I figured, new board, better technology = lighter fuse. I still had the original board in my desk so I grab a 5amp, plopped it in and all was well.

Today, closed my doors a little earlier and treated the team to a round of pinball. I'm in the middle of an awesome ball and start powerball mania. Again, I get the ball to the mini PF, start firing the magnets and.... Dead! Another blown fuse.

Sorry for the long story, but should I follow the original spec for the game or does Rottendog have it right with the 5amp and my problem is elsewhere? Maybe too many mods

I've already sent them a message. I'll let you know what I hear.

thanks pinmike. What sort of transistor did you install?

Well, the magnets work fine any other time during the game, but during the powerball mania there is a LOT going on and I suspect it's simply an issue of heavier load. Again, I'm no expert, but that's my story and I'm stickin to it

Unfortunately the game is at work so I can't get to it again until Monday. I also don't know if I'll hear from anyone at Rottendog before then either. Stay tuned.

UPDATE:

Okay, so I headed over to Playdium store at lunch and picked up some fuses (I ran out of 5 and 7 amp SB). Off topic but I also wanted to get some more time in on TF and ACDC... pretty cool.

When I got back to the office I had a reply from Jim Knight at Rottendog waiting for me.

Turns out that TZ is the one game where F112 uses a 7amp fuse instead of the 5amp he configured on his boards. Jim told me to go ahead and swap it our for a 7. Good note for any TZ owners planning on getting this board.

Thanks for this advice as well. I did open it up and found that J107 was not fully seated. I doubt it was the ultimate cause, but good to know.

Thanks all!

Hooked... where you you last week? Obviously, reading instructions and doing things in the correct order has never been one of my strengths

I have faith I'll get there one day. Thanks.
